12V DC Water Solenoid Valve 1/2 Inch Switch (Normally Closed) controls the flow of fluid and acts as a valve between high-pressure fluid! This liquid valve would make a great addition to your robotic gardening project. There are two (Nominal NPT) outlets. Normally, the valve is closed. When a 12V DC supply is applied to the two terminals, the valve opens and water can push through.

The valve works with the solenoid coil which operates electronically with DC 12 volt supply. As it is a normally closed assembly, it opens the flow of fluids as soon as it is powered ON and stops/blocks the flow when the supply voltage removed.

Note: While Connecting Valve in Flow pipeline, you need to mind the Input and Output direction of the valve. It will work only if you connect it in the right direction.

FT232RL USB to TTL 3.3V 5V Serial Adapter Module is a basic breakout board for the FTDI FT232RL USB to serial IC.

The major difference with this board is that it brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded. This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto reset any Arduino board that has the reset pin brought out to a 6-pin connector.

The pins labeled BLK and GRN correspond to the colored wires on the FTDI cable. The black wire on the FTDI cable is GND, green is CTS. Use these BLK and GRN pins to align the FTDI basic board with your Arduino target. This board has TX and RX LEDs that make it a bit better to use over the FTDI cable. You can actually see serial traffic on the LEDs to verify if the board is working.
